CHARLES KRUPA: ASSOCIATED PRESS LOUD AND CLEAR: Cowboys defensive coordinator Rob Ryan says he can't help being controversial sometimes. "I'm an emotional guy. Who are we kidding? I'm not some guy (who) just can handle coachspeak and be boring."

The Cowboys are counting on Rob Ryan to produce improved results with much the same roster that set dubious club records for yards and points allowed last season.

Even as speculation increases that he could be in line for a head coaching job after the season, Rob Ryan said Friday he remains focused solely on helping the Dallas Cowboys win a Super Bowl.

"That's the only thing we're here to do … try to win championships. That's what we're going to do," the defensive coordinator said. "About the speculation, I mean, shoot, I've speculated my whole life. It's no big deal.

"Those opportunities come when you work hard and take care of the job you have. That's what I am trying to do."

Several media outlets bandied Ryan's name about after Jacksonville fired Jack Del Rio this week. Other coaches on the hot seat as the regular season winds down include Philadelphia's Andy Reid and San Diego's Norv Turner.

But in his weekly appearance with the media at Valley Ranch, Ryan insisted his attention hasn't been diverted from helping the NFC East-leading Cowboys (7-4) beat Arizona (4-7) on Sunday.

Ryan won two Super Bowl rings as New England's linebackers coach from 2000-2003.

"There are some great feelings in the world, some great experiences," Ryan said. "Having kids is a great experience. Marrying the right girl is a great experience. Winning a Super Bowl is something else.

It's hard to say what's better. … That's (winning a championship) what we want to do."

Ryan, though, admitted that his twin brother Rex's success with the New York Jets has increased his desire to become a head coach.

"Two (AFC) championship (games) in two years, that's exciting," he said. "Do I have the talent enough to do that job? Absolutely."

Jones OK with role

Felix Jones' limited role in the Cowboys' 20-19 win over Miami last week included zero carries, but the veteran said he has no complaints.

"What's the point of tripping or anything like that?" he told reporters in Irving. "We won; that's all that matters."

Jones said he's happy for rookie DeMarco Murray, who became Dallas' No. 1 back while Jones missed four games with an ankle injury.

In the last six games, Murray rushed for 761 yards, eclipsing Emmitt Smith's franchise record for that span by 17 yards.

"It's all about friendly competition between us," Jones said.

Injury report

Miles Austin has been ruled out for a fourth straight game, but the Pro Bowl receiver is confident he will be ready to participate in the Dec. 11 showdown with the New York Giants.
